As a Software & Data/AI Engineer, you will be tasked with the intricate process of analyzing both structured and unstructured datasets. Your primary objective will be to identify commonalities across these datasets, organize them into a uniform structure, and perform entity resolution on the unstructured data. This will require a deep understanding of Python development and a proven track record of handling diverse data types.

You will be expected to leverage your strong AI experience—particularly with large language models and GenAI—to implement a Chatbot‑style interface that serves as a critical touchpoint for stakeholders.

Your role will also involve the design, architecture, and prototyping of complex AI‑based systems that are essential for the organization’s data management strategy. The technical toolkit should include proficiency with vector databases and SQL, as well as a solid grasp of user interface implementation using frameworks such as React or Angular. Familiarity with AWS cloud architecture will be crucial, as you will be responsible for deploying AI models that process a wide array of structured and unstructured data formats.

You will also clean data for ingestion and analysis to ensure optimal AI model performance.

To excel in this position, you should bring experience in AI model optimization and be capable of integrating large language model chatbots and vector databases. Your success will be measured by your ability to seamlessly integrate AI models that manage diverse data formats and by your innovative approach to AI‑based architecture that streamlines data processes and sets new standards for data management.
